The long term goals are
- Easier refactoring
- Identify needs for reflection API
Shorter term, if I want to rename `App` to `Command` and deprecate
`App`, it will mark all member access as deprecated. This works around
that.
I gave up in exploring abstractions when it came to `MKeyMap` access.
This can be refined in the future.
Now that we can use `SubcommandRequired |
ArgRequiredElseHelp`, this setting offers little value but requires we
track required subcommands with two different settings. Deprecating as
the cost is not worth the benefit anymore.
Issue #3280 will see the derive updated
This is a part of #2717
Some settings didn't get getters because
- They are transient parse settings (e.g. ignore errors)
- They get propagated to args and should be checked there
`is_allow_hyphen_values_set` is a curious case. In some cases, we only
check the app and not an arg. This seems suspicious.
I have access to the `clap-man` name but we use `clap_*`. Rather than
people getting mixed up on which is supposed to use, we went with a
different name.
